“…Given the importance of the use of Y-STR in forensic analysis, extensive population databases of haplotype frequencies are necessary to allow for calculating the probability of coincidence between two genetic profiles, and an analysis of the possible population substructure, both highly dependent on the amount of information available. In addition to the existence of a large number of publications with the participation of numerous laboratories around the world (for example, Chen et al 2018;Caputo et al 2019;Jankova et al 2019;Ambrosio et al 2020;Claerhout et al 2020;Hakim et al 2020;Adnan et al 2020;Bini et al 2021;Fang et al 2021;Babić Jordamović et al 2021;Neyra-Rivera et al 2021;Adnan et al 2022;Albarzinji et al 2022;Ashirbekov et al 2022;Dooley et al 2022;Mihajlovic et al 2022;Pamjav et al 2022;Tätte et al 2022;Ashirbekov et al 2023;Lee et al 2023), an online database was created, the YHRD-Y chromosome haplotype reference database (https://yhrd.org/) containing haplotype profiles of the markers most used in forensic genetics, for a high number of populations. In addition to making it possible to search for haplotypic profiles in various populations, the YHRD contains relevant information regarding Y-STRs for forensic use.…”

Difficulties in Kinship Analysis for Victims’ Identification in Armed Conflicts

Regarding human identification in armed conflicts, various complications can be observed. Usually, such difficulties can be social-related, which can include the lack of access to the relative’s genetic material, or the unwillingness of administrative and judicial authorities to participate in the process of identification. In the case of genetics, the analysis allows identifying the individual from a blood sample, a part of an organ, or from skeletal remains, which is why it is considered a much more extensive and effective method when compared with fingerprint techniques or odontology. However, several factors can prevent this identification, such as considerably degraded genetic material. For successful identification, it is mandatory to have access to antemortem biological samples unequivocally attributed to the individual in question, using recombinant nuclear markers, as well as using biological samples from close relatives, whether parents or sons. Nevertheless, the problems associated with armed conflicts make this type of study very difficult. In this article, we focus on the main difficulties encountered when identifying an individual victim of an armed conflict, as well as on the possibilities that exist and on viable measures that could be required to improve the identification of these victims.
